目的 精准掌握陕西榆林市羊寄生虫病的流行态势，以及养殖场（户）对寄生虫病的认知和防控状况，进而降低羊寄生虫病风险，推动当地养羊业健康发展。 方法 采用问卷调查与实验室检测相结合的方法，2024年6‒7月对榆林市12个县（市、区）的240个养殖场（户）展开调查，同时采集360份羊粪便和360份羊血液样本进行实验室分析。 结果 240个养殖场（户）均开展羊驱虫工作，其中237场（户）每年驱虫1~3次，主要使用伊维菌素等西药，通过灌服或肌肉注射给药。粪便检测结果发现，线虫、吸虫、绦虫和球虫的感染率分别达41%、31%、17%和76%，球虫和线虫感染较为严重，未发现包虫感染。 结论 尽管全市养殖场（户）驱虫率达100%，但多数场（户）驱虫药物选择单一，且防治知识不足。羊寄生虫病感染情况仍较复杂，应加强知识培训、优化养殖管理并强化防控工作。

Objectives The epidemic situation of parasitic diseases in sheep in Yulin City, Shaanxi Province, and the awareness of prevention and control of farmers (farms) regarding these parasitic diseases was accurately understood to reduce the risk of parasitic diseases in sheep and promote the healthy development of local sheep industry. Methods A survey was conducted from June to July 2024 on 240 sheep farms (households) in 12 counties (cities, districts) of Yulin City with a combination of questionnaire survey and laboratory testing. Simultaneously, 360 samples of sheep feces and 360 samples of sheep blood were collected for laboratory analysis. Results All 240 sheep farms (households) conducted deworming work on their sheep. Among them, 237 farmers dewormed their sheep 1-3 times a year, mainly using western medicines such as ivermectin, administered by oral or intramuscular injection. The results of fecal examinations showed that the infection rate of nematodes, trematodes, cestodes, and coccidia was 41%, 31%, 17%, and 76%, respectively. The infection of coccidia and nematodes was relatively severe, and no echinococcosis was detected in the serum testing. Conclusions Although the deworming rate of all livestock farms (households) in the city has reached 100%, most of them have a single choice of deworming drugs and insufficient knowledge of prevention and control. The infection situation of parasitic diseases in sheep is still complex, and knowledge training should be strengthened, management of farming should be optimized, and measures for prevention and control should be intensified.
